Science is awesome! By using a laser, check out what this graphene-based paper can do.
Originally, I found this over at Gizmodo. I also found a little more at nature.com. It is reported that this technology may be used for “robot muscle” and several-molecule-thin popup displays. It works by a laser (or heat) forcing moisture out of the material. When dry it folds one way and when moistened by humidity in the air it bends the opposite. I wonder if it will lead to self-folding origami?
